Module SwscaleSource

This module perform image scaling and color space/pixel format conversion operations.

Sourceval version : unit -> int

Sourcetype t
Sourceval create : flag list -> int -> int -> pixel_format -> int -> int -> pixel_format -> t

Swscale.create flags in_w in_h in_pf out_w out_h out_pf create a Swscale.t scale context with the flags flag list defining the conversion type, the in_w width, in_h height and in_pf pixel format for input format and out_w width, out_h height and out_pf pixel format for output format.

Sourcetype planes = (Avutil.data * int) array
Sourceval scale : t -> planes -> int -> int -> planes -> int -> unit

Swscale.scale ctx in_planes y h out_planes off scale the h rows of in_planes strarting from the row y to the off row of the out_planes output.
